FLUSH-TANK APPARATUS- SPEGIFIGATION forming part of Letters Patent No.754,247, dated March 8, 1904.

Application filed April 21, 1903.

To all whom it may concern.-

Be it known that we, JAMES H. SEAGER and JOHN J. KELLY, citizens of theUnited States, residing at Flushing, in the county of Queens and Stateof New York, have invented certain new and useful Improvements in Flush-Tank Apparatus, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make anduse the same.

This invention relates to the flush-tanks of water-closets; and theobject thereof is to provide improved means for controlling the flow ofthe water into tanks of this class, a further object being to providemeans to prevent the hammering which almost always acconhpanics theoperation of apparatus of the class, and thus avoid a very disagreeablefeature thereof.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof our improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a sectional side View of apart of a flush-tank provided with our improvement, which is shown infull lines; Fig. 2, a similar view showing the improvement in centralvertical section; Fig. 3, a sectional plan vie; of the improvementremoved from the tan In the drawings forming part of this specificationthe means for conveying water from the tank to the basin or otherarticle to be flushed is not shown, this invention relating only to themeans for conveying the water into the tank, and in the practice of ourinvention we provide a casing a, having at its lower end ascrew-threaded member if, which passes through the bottom of the tank 6,and which is preferably packed both above and below said bottom, asshown at b and b and connected with the lower end thereof is a pipe 0,which serves as a water-supply pipe. We also provide a piston or valvecasing 03, which is arranged transversely of the top of the easing a andprovided at the bottom thereof with a screw-threaded member d which isscrewed into the top of the casing a, and which is pro- Serial No.153,708. (No model.)

vided with a downwardly directed tubular member d, which extends almostto the bottom of the casing 61- and around which is an annular chamberor space-e, which is in free communication with the interior of thescrewthreaded member (l of the casing a, which passes through the bottom6* of the tank Z2.

Within the valve or piston casing d is a horizontally arranged chamberd, one end of which is closed by a screw-threaded plug (i and the otherend of said casing is extended and provided with a longitudinal borediwhich is closed by a cap d in the usual manner, and passing throughthe bore (Z and the cap (Z is a piston or valve rod 6 the inner end ofwhich is connected with a piston or valve 6 within the piston or valvechamber (2, and one side, preferably the bottom, of the extension of thecasing '03 is provided with a large port or passage f, whichcommunicates with the bore d", and said bore (2 is much larger indiameter than that part of the piston or valve rod 6 which passestherethrough.

Pivotally connected with the top portion of the extension of the casing03 at g is an arm g to which is pivoted at g a crank-yoke g to which theouter end of the piston or valve rod 6 is pivoted at 9 and saidcrank-yokeis provided with a projecting member through which passes ascrew g provided with a thumbnut g", and the head portion of said screwon the side of the projecting member g opposite the thumb-nut g isprovided with a transverse passage 5 through which passes a float-rodla, with which is connected a float [L and by means of the thum b-nut gthe position of the rod It in the head of the screw 9 may be adjusted soas to bring the float if nearer to or farther from the valve or pistonrod 6 as may be desired.

The central bore of the tube d within the casing a communicates with thepiston or valve chamber 03' near the inner end of said chamber, and thepiston or valve 6 is designed to close and open said bore in theoperation of the apparatus as hereinafter described, and it will beunderstood that by means of the thumbnut g the float k may be rigidlyheld in any desired position, as the head of the screw g is cylindricalin form and movable through the extension or projection g of thecrank-yoke g, and the thumb-nut thus serves both as a means foradjusting the position of the rod la and also for locking it in anydesired position, and the said rod forms practically an extension of thearm g and it is by this arm and the float k that the valve or piston ais operated, said valve or piston being operated directly by the floatIf, the operative connection of which is with the arm 9.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings and thefollowing statement thereof: It will be understood that the water isfree to flow at all times through the pipe 0, and supposing the tank 5to be empty and the float k to be in its lowest position the passagethrough the pipe d and through the chamber (l and the bore (1 and theoutlet port or passage f will also be open, and the water will rise intothe interior of the casing and pass through the pipe d and through thechamber (11* and the bore (1 and the port or passage f into the tank 6,and when the water reaches the desired height in said tank the float itwill be raised in the position shown in Fig. 2' and the piston or valve0 will close the passage through the pipe (i and cut off the flow ofwater into said tank. It will be understood that in the operation offlushing the water is discharged from the tank I) by the usualapparatus, which is not shown, and in this operation the float 7? fallsand the rod e is forced inwardly, and the passage through the pipe (Z isagain opened, and the water is again free to flow into the tank untilthe float rises to the position shown in Fig. 2, when the passagethrough the pipe (Z and its connected parts will be again cut oil.

It is a well-known fact that in the operation of apparatus of this classthe flow of water through the pipe 0 into the tank, as hereinbeforedescribed, produces a hammering which is very objectionable; but withour improvement the chamber e in the casing a is filled with air, whichforms a cushion, and when the water flows into the tank, as hereinbeforedescribed, and especially atthe time when the operation of the float kcloses the passages through the pipe (Z this air-cushion serves toprevent the hammering of the water referred to or the force of saidwater is taken up by the air-cushion and no sound of hammering isproduced.

This device is simple in construction and comparatively inexpensive andmay be employed wherever apparatus of this class is desired, and it willbe apparent that changes in and modifications of the constructiondescribed may be made without departing from the spirit of our inventionor sacrificing its advantages.

Having fully described our invention, what we claim as new, and desiretosecure by Letters Patent, is-

A water-supply device for flush-tanks, comprising a main casing one endof which is adapted to be secured in the bottom of a tank; asupplemental casing detachably connected with the top thereof andranging transversely thereof and one end of which is closed by a removable plug and the other end of which is provided with an extensionhaving a longitudinal bore, said supplemental casing being also providedwith a tube which projects downwardly into said main casingapredetermined distance and with ahorizontal valve-chamber communicatingwith said tube and with said horizontal bore and between which and saidbore is a valve-seat; a valve mounted in said valve-chamber and adaptedto close the communication with said tube and provided with a valve-rodwhich passes through said bore and outwardly through the end of saidextension, said end being closed by a removable cap; and a floatrodloosely connected with said supplemental casing at the top thereof andin operative connection with the outer end of said valve-rod,substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of the subscribing witnesses, this 20th day ofApril, 1903.
